Bug #65634 [Opn->Nab]: HTTP wrapper is very slow with protocol_version 1.1

Edit report at https://bugs.php.net/bug.php?id=65634&edit=1 ID: 65634 Updated by: aharvey@php.net Reported by: butesa at freenet dot de Summary: HTTP wrapper is very slow with protocol_version 1.1 -Status: Open +Status: Not a bug Type: Bug Package: HTTP related Operating System: Ubuntu 12.04 x64 PHP Version: 5.5.3 Block user comment: N Private report: N New Comment: Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php www.google.de responds with a keep-alive connection when a HTTP/1.1 request is made and no Connection request header is included, which is valid in RFC 2616. Sending a "Connection: close" request header restores the 1.0 behaviour. Previous Comments: ------------------------------------------------------------------------ [2013-09-08 16:27:47] butesa at freenet dot de Description: ------------ Loading a website with the http wrapper takes very long if protocol_version is set to 1.1. The time it takes depends on the timeout. On some servers the problem doesn't occur. I tested also on Ubuntu 10.04 (PHP 5.3.2-1ubuntu4.19) and Ubuntu 12.04 (PHP 5.3.10-1ubuntu3.7), both 64bit. Test script: --------------- <?php $url = 'http://www.google.de/intl/de/policies/?fg=1'; foreach(array(1.0,1.1) as $proto) { for ($timeout = 1; $timeout < 60; $timeout+=10) { $st = microtime(true); $opt = array( 'http' => array( 'timeout' => $timeout, 'protocol_version' => $proto, ), ); $context = stream_context_create($opt); $content = file_get_contents($url,false,$context); printf("%2d %.1f %f %s\n", $timeout, $proto, microtime(true) - $st, md5($content)); } } ?> Expected result: ---------------- The request takes the same time, no matter what timeout and protocol_version is set. Actual result: -------------- Output of the test script: For $url='http://www.google.de/intl/de/policies/?fg=1': 1 1.0 0.279102 60bf7bc72d2a06b337c8a8464e0f9e66 11 1.0 0.277956 60bf7bc72d2a06b337c8a8464e0f9e66 21 1.0 0.283753 60bf7bc72d2a06b337c8a8464e0f9e66 31 1.0 0.285862 60bf7bc72d2a06b337c8a8464e0f9e66 41 1.0 0.277894 60bf7bc72d2a06b337c8a8464e0f9e66 51 1.0 0.285653 60bf7bc72d2a06b337c8a8464e0f9e66 1 1.1 2.284301 60bf7bc72d2a06b337c8a8464e0f9e66 11 1.1 22.305424 60bf7bc72d2a06b337c8a8464e0f9e66 21 1.1 42.309270 60bf7bc72d2a06b337c8a8464e0f9e66 31 1.1 62.355997 60bf7bc72d2a06b337c8a8464e0f9e66 41 1.1 82.360794 60bf7bc72d2a06b337c8a8464e0f9e66 51 1.1 102.379933 60bf7bc72d2a06b337c8a8464e0f9e66 For $url='http://www.example.com': 1 1.0 0.491382 09b9c392dc1f6e914cea287cb6be34b0 11 1.0 0.426191 09b9c392dc1f6e914cea287cb6be34b0 21 1.0 0.428513 09b9c392dc1f6e914cea287cb6be34b0 31 1.0 0.423852 09b9c392dc1f6e914cea287cb6be34b0 41 1.0 0.423751 09b9c392dc1f6e914cea287cb6be34b0 51 1.0 0.431590 09b9c392dc1f6e914cea287cb6be34b0 1 1.1 1.420486 09b9c392dc1f6e914cea287cb6be34b0 11 1.1 6.143113 09b9c392dc1f6e914cea287cb6be34b0 21 1.1 5.994384 09b9c392dc1f6e914cea287cb6be34b0 31 1.1 5.991940 09b9c392dc1f6e914cea287cb6be34b0 41 1.1 6.012121 09b9c392dc1f6e914cea287cb6be34b0 51 1.1 6.007920 09b9c392dc1f6e914cea287cb6be34b0 For $url='http://www.php.net': 1 1.0 1.673016 2dcc6fe85b335205a35d9980a9095735 11 1.0 1.935555 2dcc6fe85b335205a35d9980a9095735 21 1.0 1.648235 2dcc6fe85b335205a35d9980a9095735 31 1.0 1.637566 2dcc6fe85b335205a35d9980a9095735 41 1.0 1.633473 2dcc6fe85b335205a35d9980a9095735 51 1.0 1.718051 2dcc6fe85b335205a35d9980a9095735 1 1.1 1.647803 2dcc6fe85b335205a35d9980a9095735 11 1.1 1.863799 2dcc6fe85b335205a35d9980a9095735 21 1.1 1.673567 2dcc6fe85b335205a35d9980a9095735 31 1.1 1.651704 2dcc6fe85b335205a35d9980a9095735 41 1.1 1.657976 2dcc6fe85b335205a35d9980a9095735 51 1.1 1.635651 2dcc6fe85b335205a35d9980a9095735 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65634&edit=1
